Tomcat 5和Tomcat 6配置ssi支持的区别

在Tomcat中配置ssi支持的时候，Tomcat 5和Tomcat 6是有区别的，先说相同的地方，找到$CATALINA_HOME/conf/web.xml中的下面两段被注释掉的部分，并将取消注释。 

<!--        <servlet>            <servlet-name>ssi</servlet-name>            <servlet-class>              org.apache.catalina.ssi.SSIServlet            </servlet-class>            <init-param>              <param-name>buffered</param-name>              <param-value>1</param-value>            </init-param>            <init-param>              <param-name>debug</param-name>              <param-value>0</param-value>            </init-param>            <init-param>              <param-name>expires</param-name>              <param-value>666</param-value>            </init-param>            <init-param>              <param-name>isVirtualWebappRelative</param-name>              <param-value>0</param-value>            </init-param>            <load-on-startup>4</load-on-startup>        </servlet>    -->    <!--        <servlet-mapping>            <servlet-name>ssi</servlet-name>            <url-pattern>*.shtml</url-pattern>        </servlet-mapping>    -->  

然后对于Tomcat 5需要将$CATALINA_HOME/server/lib下的servlets-ssi.renametojar文件改名成servlets- ssi.jar，否者会出现Java.lang.ClassNotFoundException: org.apache.catalina.ssi.SSIServlet错误。
而对于Tomcat 6 需要将$CATALINA_HOME/conf/context.xml中 结点添加一个属性 privileged=&quot;true&quot;变成，如果没有加的话则会出现java.lang.SecurityException: Filter of class org.apache.catalina.ssi.SSIServlet is privileged and cannot be loaded by this web application 错误。
